We analyze the short and long run effects of demographic ageing - increased longevity and reduced fertility - on per-capita growth. The OLG model captures direct effects, working through adjustments in the savings rate, labor supply, and capital deepening, and indirect effects, working through...

This paper empirically examines the effect of population growth on real interest rates. Although this effect is well founded in macroeconomic theory, the corresponding empirical results have been rather tenuous. Demographic interest rate theories are typically based on long-term relationships...

The level of financial development is an important determinant of the performance of capital markets. We examine stock returns in a cross section of emerging and mature markets (49 countries) over 1980-99. Returns in financially underdeveloped countries have been somewhat lower, but...

We develop a general equilibrium model of vertical innovation in which multiple firms compete monopolistically in the quality space. The model features many firms, each of which holds the monopoly to produce a unique quality level of an otherwise homogenous good, and consumers who are...

We analyze the effect of changes in fertility and longevity on taxes, the composition of government spending, and productivity. To that purpose, we introduce politics in an OLG economy with endogenous growth due to human and physical capital accumulation. Population ageing shifts political power...

We analyze the effect of the projected demographic transition on the political support for social security, and equilibrium outcomes. Embedding a probabilistic-voting setup of electoral competition in the Diamond (1965) OLG model, we find that intergenerational transfers arise in the absence of...

While the direct impact of geographic endowments on prosperity is present in all countries, in former colonies, geography has also affected colonization policies and, therefore, institutional outcomes. Using non-colonized countries as a control group, I develop an empirical strategy that...

The empirical literature on nominal exchange rates shows that the current exchange rate is often a better predictor of future exchange rates than a linear combination of macroeconomic fundamentals. This result is behind the famous Meese-Rogoff puzzle. In this paper we evaluate whether parameter...

Does a country's ability to enforce debt contracts affect the sensitivity of economic activity to collateral values? To answer this question, we introduce a novel industry-specific measure of real asset redeployability - the ease with which real assets are transfered to alternative uses - as a...

We explore the effect of foreign direct investment on economic growth in developing countries, distinguishing between mergers and acquisitions ("M&As") and "greenfield" investment. A simple model captures the key difference between the two types of FDI: unlike greenfield investment, M&As partly...
